    Big Red 250ES guys...what psi do you run in your stock Ohtsu tires?

    The manual suggests 2.2-2.5 psi, but that seems pretty low...what say you?

    From 2-4 depending on ride comfort..not over 5PSI you'll damage them.

    I suggest you invest in a low pressure tire gauge..I bought a couple on Ebay. Most pressure gauges start at 10 PSI

    Yeah I have mine at 2.5 psi right now, it seems to make the bike sit too low in the rear though. I may try 3.5-4 psi. I have the low pressure gauge that came with the tool kit luckily.
